Rewriting to point to a CDN
jp flag

I'm hoping to use a CDN to deliver all our image files. We call the images by simply using the CDN's domain instead of our own. I could easily change the domain reference in our content management system, but then preview breaks because it's looking for an image that doesn't yet appear on our external server for our CDN to pull from. As soon as we publish, the CDN has an image to pull.

Kubernetes Nginx Ingress Controller Metrics
gu flag

I've tried to find a documentation about the metrics exposed by the NGINX ingress controller in Kubernetes but so far I haven't found any reliable source about the metrics and what they mean.

For example, there are three different request_size metrics (sum, bucket, count).

From my guessing sum and count correlate with each other. And to get the average request size I could probably do something like

VPN IPsec site connection sporadically lost data between Openstack VPN and a Checkpoint firewall

We have established an IPsec VPN site connection from our Openstack to a Check Point firewall device.

The tunnel is UP but sporadically the connection has "breaks". We already checked between the configs on both sides if anything was different but that doesn't seem to be the case.

But even though the configuration is the same on both sides, the breaks are still there.

On the Openstack side we are using  ...

Fedora Server: Is there a security feature that prevents drag-and-drop onto a VirtualBox VM (host: Windows 10)?

Not sure if it's the right part of the forum to post this, but I've just created a VM on VirtualBox with the latest Fedora Server as guest, and everything went fine.

I need to set up multi-source replication (3 masters and 1 slave). Since all masters have users with the same name but not the same rights, I'd like to avoid replicating users' changes on the slave because it breaks replication.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
